How to pass the excel file path from one wrkflow to another workflow using argument?



I have got excel file created from workflow 1 and now I want to use that excel file for another workflow 2. I have to do this using argument globally that will store the excel file path in workflow 2 and pass it to workflow 2.
I used an argument in wrkflw 1 assigning it a path. and have used that argument in wrkflw 2 in read range. But I am getting an error: “Invoke Excel Updation Extracted workflow: Excel application scope : Value cannot be null.
Parameter name: path”. Can anyone please let me know how I can use this?
